Subject [jira] Commented: (CAMEL-2899) out of heap space if remote FTP site has too many files to pick up
Date Fri, 02 Jul 2010 17:07:52 GMT


Karl Palsson commented on CAMEL-2899:

Seemed very reasonable, but unfortunately, it doesn't help....

2010-07-02 17:02:42,327 FATAL Consumer Consumer[ftp://sms02@localhost:2121/autre
ed&passiveMode=true&password=sms02] could not poll endpoint: ftp://sms02@localho
move=.processed&passiveMode=true&password=sms02 caused by: Java heap space
java.lang.OutOfMemoryError: Java heap space

I tried again without file filter, (just an ant pattern name matcher) in case that was causing
any problems, but it still fails.

> java.lang.OutOfMemoryError: Java heap space
> My remote FTP server has ~60k 100 byte files, and the camel endpoint consumer falls over
and doesn't start again.  I can use JMX to stop/start the consumer, (it still has status "started")
and it will log in to the remote server again, but then fall over with the out of heap space.
> I can work around this by increasing the heap, or by moving some of the files aside,
 but I don't think camel should care how many files there are, or at least, I think it should
deal with it more gracefully.
