Upgraded 6.0.7 on Ubuntu 8.04 to 6.0.8 on Ubuntu 10.04

[y@w]

Fairly smooth except I hit a dependency that wasn't checked during the installer: Bug 50179 – libltdl not being checked as dependency

I also lost my zimbraMailMode again

It appears I'm also hitting this: Bug 42870 – "Bad file descriptor" SocketException causes system failure every several hours

I am running Debian 5 64-bit 6.07 on Ubuntu 10.04 64-bit and was getting this every few hours too.

Put in this recommended fix from the bug thread and haven't had it since - I didn't comment it out but changed both 65536 to 204572.

Not sure if this will help, but we were having file descriptor limit problems
on each of our servers with 6.0.4 immediately after upgrading as well, despite
the zimbra user being set to 524288. I noticed something new in
/opt/zimbra/jetty/etc/jetty-setuid.xml... Near the end, there is a section that
wasn't present in 5.0.18 that looks like this:

<Call name="setRLimitNoFiles">
<Arg>
<New class="org.mortbay.setuid.RLimit">
<Set name="soft">65536</Set>
<Set name="hard">65536</Set>
</New>
</Arg>
</Call>

Thanks Jim, I bumped up the max number of open files for root as well like the bug said and all seems fine now. Doesn't really make sense to me why root would need that, but the issue happened twice in one day and hasn't come back now in a week, so it appears as though it's "fixed".
