Bamboo sometimes fails on sshd-SshClient thread

Hello All!

My Bamboo fails about once a week. When it fails, there is no high load. The Java process of Bamboo just disappears. The respective files hs_err_pid*.log show that failures are in java.math.BigInteger.montReduce and the then-current threads have "sshd-SshClient" in the beginning of their names.

The typical beginning of one of such files hs_err_pid*.log looks like the text below:

#
# A fatal error has been detected by the Java Runtime Environment:
