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.
