It means that your apache hasn't been shutdown properly - it failed to remove the shared memory segments it allocated. You have two options at this point: - reboot the server - use the ipcs -m command to list the shared memory segments and then ipcrm -m shmid for each of the former apache segments (you can tell which belonged to apache by the owner - it will be the user apache runs as). Before removing the segments, though, make sure that you stop apache. hope that helps, marek signature.asc Description: PGP signature ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list

Re: [Mono-list] mod_mono still not working after an upgrade
Hi Marek, I am very glad that my problem is being taken seriously. Applying the patch would be difficult as I am using the approved SUSE 10.2 rpm file. I did have a go, but lack apxs and some other required installations. (SUSE 10.2 seems to be missing many apache/mono development packages?) As well, installing source over a working SUSE installation I have found, from bitter experience, usually make SUSE fail all over the place, especially yast2. I don't have an available development box. Sorry! I am happy to know that a fix is in the system and I will look out for the next apache2-mod_mono-x.x.x.i586.rpm and apply that. In the mean while I will continue to # apache stop ; kill -9 mod_mono ; apache start.

Can you test the attached patch by applying it to mod_mono sources and
recompiling the module? Please let me know if it fixes your problem,
thanks,

What are the permissions on the mentioned file at that point? Is it able to be deleted by the Apache process (could depend on permissions on /tmp too). You might try adding: export MOD_MONO_LOCKING_MECHANISM=FLOCK in /etc/sysconfig/httpd, or the equivalent, to set the var for the httpd process. -- - Josh Tauberer http://razor.occams.info "Yields falsehood when preceded by its quotation!

[Mono-list] mod_mono still not working after an upgrade
Dear Mono, I am still having terrible problems getting mod_mono working after an upgrade to SUSE 10.2. I get lots of errors like: [Tue Sep 25 14:24:20 2007] [crit] Failed to remove dashboard file '/tmp/mod_mono_dashboard_XXGLOBAL_1', further actions impossible. Operation not permitted The only way to reliably start mono seems to be to stop apache, kill all instances of mod_mono which have failed to stop, and restart apache. The mono control panel doesn't work at all. This causes downtime on servers which should never need downtime. I have seen lost of postings about this, but none of the suggested fix's seem to work. I have this directive in a virtual host: -- AddMonoApplications main_webservice "/ws:/usr/local/ws/" MonoMaxMemory main_webservice 134217728 MonoSetServerAlias main_webservice SetHandler mono Order allow,deny Allow from all SetHandler mono-ctrl Order Deny,Allow Allow from 172.16 -- Please please if any person knows how to fix this, and recover my serious failing opinion of mod_mono, can they let me know!
