Hi all. I have a tomcat setup that works through mod_jk-1.2.5 and Apache 1.3.28, running on Solaris 7 and Solaris 8 boxes. I've found what appears to be a file descriptor leak. I haven't been able to find mention of this on http://marc.theaimsgroup.com/?l=tomcat-user, or in apache's bug reporting database.
I was hoping to see whether anyone else had seen similar behavior, or if anyone else could reproduce it. After a cold start, this is what the list of open fd's looks like. "one_mod_jk_log" and "two_mod_jk_log" are files named by JkLogFile directives (there are two JkLogfile directives, each in a different VirtualHost container in srm.conf). $ lsof -p `cat /etc/httpd.pid ` | grep _jk httpd 21307 root txt VREG 136,0 834728 958215 /l/apache/libexec/mod_jk.so httpd 21307 root 4u VREG 136,0 3023 848146 /l/apache/logs/localhost/two_mod_jk_log httpd 21307 root 5u VREG 136,0 3023 848147 /l/apache/logs/localhost/one_mod_jk_log httpd 21307 root 6u VREG 136,0 3023 848146 /l/apache/logs/localhost/two_mod_jk_log httpd 21307 root 7u VREG 136,0 3023 848147 /l/apache/logs/localhost/one_mod_jk_log After signaling the server to restart, the number of open descriptors increases. (/etc/httpd.pid is Apache's PidFile). $ kill -HUP `cat /etc/httpd.pid ` $ lsof -p `cat /etc/httpd.pid ` | grep _jk httpd 21307 root txt VREG 136,0 834728 958215 /l/apache/libexec/mod_jk.so httpd 21307 root 4u VREG 136,0 5028 848146 /l/apache/logs/localhost/two_mod_jk_log httpd 21307 root 5u VREG 136,0 5029 848147 /l/apache/logs/localhost/one_mod_jk_log httpd 21307 root 6u VREG 136,0 5028 848146 /l/apache/logs/localhost/two_mod_jk_log httpd 21307 root 7u VREG 136,0 5029 848147 /l/apache/logs/localhost/one_mod_jk_log httpd 21307 root 8u VREG 136,0 5028 848146 /l/apache/logs/localhost/two_mod_jk_log httpd 21307 root 9u VREG 136,0 5029 848147 /l/apache/logs/localhost/one_mod_jk_log After the HUP, there are two additional file descriptors open. Another HUP will open up two more, and so forth. USR1 (aka apachectl graceful) seems to produce similar results. The problem really shows itself with log rotations; you need to restart the server in order to have it close and reopen its logfiles. But in this case, the parent httpd process eventually runs out of file descriptors and dies. :( mod_jk-1.2.3 shows the same behavior. If any of the other mod_jk/apache users wouldn't mind trying to reproduce this, I'd very much appreciate knowing what you found. Likewise, if anyone could offer a pointer to a workaround. Thanks in advance. -- Steve --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
