So I have a redundant pair of management servers running on 4.2.1. At least
once a day one of the management servers crashes and the log gets filled with
the following messages:
java.lang.OutOfMemoryError: Java heap
spac0java.lang.ArrayIndexOutOfBoundsExceptioneCaused by: java.io.EOFException:
SSL peer shut down incorrectlyCaused by: javax.net.ssl.SSLHandshakeException:
Remote host closed connection during handshake
and there are a few others. When the one management server tanks, although the
other management server is up and active, it won't actually process any UI
commands until the crashed server is powered off. Example of process any UI
command is create a new instance, create a new account, etc. After doing some
searching I have found that others have noticed java heap errors in 4.2.1, and
the suggested fix is to increase the heap size. I am planning on increasing it
from 2g to 4g, however if the problem is something like a memory leak, then
increasing the heap size will just delay the inevitable. Has anyone else fixed
this issue by increasing the heap size? Or what is the recommended value?
In my honest opinion of bigger concern is the fact that when one management
server crashes the other stops functioning as well. So this begs the question
of why even bother with a redundant pair of servers..Anybody else experience
this issue? I would love to hear any dev guys opinion on this as well.
