Enterprise manager crashes

[nkarthik]

Hi,

Can someone tell me whether below error will cause enterprise manager to go down? And if it does, whether this error will be followed by any other specific errors.

plz elaborate!

Our enterprise manager goes down suddenly. And we are seeing this error continuosly in our logs. As per my concerns, I dont think this is the direct cause. There could be some other thing which is causing the EM to go down. So I would like to know if this error will really cause some issues.

Change the "ulimit" option for open files to at least 65536.

Hi,

I am seeing below error first in logs before EM crashes.

Uncaught Exception in Enterprise Manager: In thread Lucene Merge Thread #0 and the message is org.apache.lucene.index.MergePolicy$Mergexception: java.io.FileNotFoundException(Too many open files)

Any idea about this error?

Thanks,
Karthik

Hi hdavis,

I have read that and we are in the process of changing ulimit. But I also would like to know about the other error as well.

Do you have any idea what this second error is about?

Thanks,
Karthik

They are all related to your "ulimit" setting so please let us know after you've changed this and restarted your EM.
