Crin1 server email problem

[chris]

Web application on Crin1 are unable to send email, when they attempt to they log this error in the /var/log/exim4/paniclog:

2015-07-09 00:43:08 unable to set gid=115 or uid=0 (euid=0): forcing real = effective

Jenny / Gillian would you like me to fix this problem? It won't take long as the solution is here:

Hi Chris,

Please can you just clarify if this is about the CRINmail being sent out blank, rather than the CRINmails bouncing back. If the former, yes please, the latter is not important.

Thanks,

Jenny

Replying to jenny:

Neither, this is an issue on Crin1, so it effects Piwik, ownCloud and MediaWiki.

This has been fixed, the following was added to /etc/apache2/mods-enabled/mpm_prefork.conf:

LimitUIDRange 0 2000

And Apache was restarted.
