Bug or INFO

[old]

Hi

INFO [btpool0-5 - Acceptor0 SslSelectChannelConnector@0.0.0.0:7071] [] log - org.mortbay.io.nio.SelectorManager$SelectSet@43849 f21 JVM BUG(s) - recreating selector 50 times, canceled keys 3246 times

this is only info? I have many items like this in my mailbox.log.

Best regards

I'm also getting this in my logs.
Jesterday I upgraded from 6.0.6 NE to 6.0.12 NE on SLES 10 x86...
Here' link for more info about jetty JVM NIO bug
Seems to me like a jvm bug workaround...
My question is, does this influences on performance? The reason for upgrade was slow responsiveness from mail server.
Thanks, regards

That is the question. There is an explanation in that file above but an insight on how does zimbra triggers it would be nice.

I'm getting the same error in my mail.log. I know it's INFO but I would like to understand if this precursor to more problems ...

This messages are nothing you have to worry about. As Aleks wrote, this is caused by Jetty workarounds implemented to deal with some JAVA JVM NIO Bugs: Jetty/Feature/JVM NIO Bug - Eclipsepedia until the bugs are being fixed.

This doesn't affect performance in any way a user might notice.
