Huge number openned log files

[Ventzy]

I have got "Too many open files" error on my server and after checking lsof I found huge number opened files for error logs.

lsof | grep /var/log/ispconfig | wc -l
150582

The server have ~ 1200 virtual hosts.
One line looks like this

COMMAND     PID       USER   FD      TYPE             DEVICE    SIZE/OFF       NODE NAME
apache2   30294   www-data  615w      REG              251,0     3276350   10237337 /var/log/ispconfig/httpd/myhost/error.log

and there are ~ 150 lines like this for single vhost.

What could cause this?

[till]

Apache opens a file handle for each error.log file of the vhosts.

There are two options:

a) Increase the max open file handles in your server.
b) comment out the error.log directive in the apache vhost template in /usr/local/ispconfig/server/conf/ and resync all vhosts. This will disable the individual error logging for the vhosts.

Thanks, we will consider the options. But is it normal to have 150 opened handles for a single log file? It seems huge number to me.
