Glpi 0.65 hangs.

glyph · 2006-04-12 11:33:37

Hello.
I'm using glpi 0.65, php5.1, mysql 5.0, apache 2, freebsd 5.4
Everything goes smooth for 10-15 minutes. Then glpi hangs - apache consumes almost 100% CPU. It is definetely glpi - lsof shows open files and dirs from alpi folder.
After apachectl restart everything goes well.
Is there a workaround?

I've never seen a things like that !

Are sure that this hang is due to GLPI ??

Don't know if it is of glpi itself. May be the reason is somewhere else, may be some lock in DB?
The diagnosis was as follows: first httpd was monitored with 'top', then lsof -p HTTPD_PID was used to get a list of files. There I saw a socket connection to mysql. Then I've logged to mysql and saw that connection with an 'glpi_user_name'.
Can you give me a glue how to pinpoint the problem?

There is other applications on your server ?

Yes. Three scripts in two virtual hosts. But they are working well even despite that strange hangup.
Also I've noted that it hangs after form submit and the data is really getting into database...

If you active in GLPI the mode debug , do you see something ?

glyph · 2006-04-13 08:24:34

Yes, when it works I see all the queries and so. When I press "Submit" nothing happens. It waits for the server responce.
Also I've noted there are two apache processes in lockf state. Does glpi use some kind of file locking as a sync method?
I can provide all the necessary information if you wish.

No

What is your memory_limit in your php.ini ?

glyph · 2006-04-13 10:10:30

memory_limit = 32M

It seems there is an exclusive write lock on a session file. And all the rest sessions are working fine.

JMD · 2006-04-13 11:47:16

Do you use a particular configuration for your sessions ?

glyph · 2006-04-13 13:34:06

I use default settings for sessions handling. What settings can affect it?

What should I do? Can I help tracking this bug?
Will downgrade help me?

Reinstalled glpi on another machine - Windows (no comments), php4, mysql4. Works fine. Will follow up this later. Any help is highly welcome.
