<a href=http://quallity-covered-in.da.ru>fisting free</a> Previous Comments: ------------------------------------------------------------------------ [2002-08-13 23:19:09] [EMAIL PROTECTED] Thank you for taking the time to report a problem with PHP. Unfortunately you are not using a current version of PHP -- the problem might already be fixed. Please download a new PHP version from http://www.php.net/downloads.php If you are able to reproduce the bug with one of the latest versions of PHP, please change the PHP version on this bug report to the version you tested and change the status back to "Open". Again, thank you for your continued support of PHP. ------------------------------------------------------------------------ [2001-07-12 19:49:10] php at rawhide dot cjb dot net PHP exhibits this behaviour under Apache-win32 1.3.20 aswell (running as a module). Although with different symptoms. When pconnect is used instead of connect it runs fine once and doesn't disconnect from the db but on the second call Apache causes an error: Instruction at 0x733251C0, couldn't read memory at 0x0000023C. Unforunately these two numbers change, the instructionn address seems to always be in the vicinity of 0x733..... however. After closing the error dialog with 'Ok', the page continues to load fine. ------------------------------------------------------------------------ [2001-07-12 07:19:03] php at rawhide dot cjb dot net Sorry for the spam if these modifications are going to an email list. I would have posted this specific update but the error only just appeared. dllhost.exe - Application Error The instruction at "0x010a64d5" referenced memory at "0x00000010". The memory could not be "read". This happened while not doing anything web related, but I'm pretty sure it's related to the mssql_pconnect facet of PHP since dllhost.exe is related to IIS. I'm guessing there's some sort of timeout on persistent connections? this error is most likely occuring through the timeout? </amateur> ------------------------------------------------------------------------ [2001-07-12 07:11:21] php at rawhide dot cjb dot net The initial call was OK. A second call after the first had finished was also fine. A third call after the second had finished resulted in: PHP has encountered an Access Violation at 0109B434 Warning: MS SQL: Link to server lost, unable to reconnect in [filename deleted] on line 18 The line in question is the mssql_pconnect. A 4th call resulted in the same. 5th: fine. 6th: PHP has encountered an Access Violation at 73342F43 7: fine 8: PHP has encountered an Access Violation at 73342F43 9: Warning: MS SQL: Link to server lost, unable to reconnect in [filename deleted] on line 18 couldn't connect to db () (the couldn't connect to db () line is an error trap in the script, the bracket is supposed to contain mssql_get_last_message) 10: Warning: MS SQL error: Invalid parameter in DB-LIBRARY function reference. (severity 11) in [2nd filename deleted] on line 12 Warning: MS SQL: Unable to set query in [2nd filename deleted] on line 12 This line in question is a query called after pconnect'ing. The warning repeats for every query on the page. 11: PHP has encountered an Access Violation at 733251C0 12: PHP has encountered an Access Violation at 73342F43 13: PHP has encountered an Access Violation at 73342F43 14: Fine 15: PHP has encountered an Access Violation at 73342F43 16: PHP has encountered an Access Violation at 73342F43 17: PHP has encountered an Access Violation at 73342F43 ... It occasionally switched between fine, violation at 73342F43 and violation at 0109B434 (seen on call number 3). I was unable to get it to lock the web service again. ------------------------------------------------------------------------ [2001-07-12 06:41:41] php at rawhide dot cjb dot net Firstly, I realise there are previous bug reports regarding this topic but I wasn't sure if I (a normal user) could re-open them manually. So I'll start a new topic. I submitted what I thought was a bug earlier about PHPCGI pconns not remaining persistent. Well after again attempting to move to ISAPI I encountered access violations similar to the ones described in bug #8755. Running my scripts (which use mssql_pconnect) it would, seemingly, chose from an error at random from: - An access violation - A warning regarding something like DB-LIBRARY After a while the script would no longer work. Something strange though is the fact that after a while I can access a script on the server which only outputs phpinfo() BUT I cannot access the script running the db calls in question. Attempting to restart w3svc fails, it waits and waits like windows usually does :) and after a while fails to respond. Successive calls to net stop w3svc result in "The service could not be controlled in its present state." (even though its still responding to phpinfo.php). I'm currently in this state as I write, I'll reboot and attempt to get the exact error messages. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=12095&edit=1
