Description

« Hide

ActiveMQ ran out of file descriptors, was accepting socket connections, but could not accept any incoming data. This put the client into a loop where it tried to:

do a graceful disconnect

that failed (fwrite raising a PHP notice)

try to reconnect

do a graceful disconnect

that failed (fwrite raising a PHP notice)

try to reconnect

do a graceful disconnect

that failed (fwrite raising a PHP notice)

....

If the loop wasn't bad enough, the PHP notices raised overwhelmed my database recording the errors.

Patch that solves this issue by blocking a reconnect attempt should a graceful disconnect fail, as well as suppressing the PHP notice on the fwrite.
