clamav error: mpool_malloc(): Attempt to allocate 8388608 bytes

Solution 1:

Yeah, it hit me too, here is the bug report: https://bugzilla.clamav.net/show_bug.cgi?id=11647

Upgrade to a new version. I guess you have 0.97 version.

Solution 2:

I have the same errors on 8 Servers since yesterday. All Server are Zimbra servers.

I have fixed the problems with updating the Zimbra to new release.

But at one i do not have the option to update.

I think it is a Bug in an old clamd release.
