Hi all,

Raising this topic for a friend.

He's configured 2 agents each of which is monitoring its respective folder. The Monitoring agent on finding a modified file invokes an Ant script which triggers a transfer. This is working smoothly.

He then tested with 20 files (images of say 1Mb) which invoked 20 instances of the Ant script and thereby 20 transfers...

This is where the agents have got hung and can't be stopped, starting agent command says agent already running. The system had to be restarted.

I read another post which mentions upgrading MQ and applying a certain fixpack...not sure of the current version as of now, will confirm that.

Any other ideas ? Can someone also suggest settings for the agent concurrent sessions, JVM size etc...

Regards.

Are you doing a call command in the ant script? If so - you will be running out of threads, and tie up the existing ones - so the transfer will just hang.
Usually agents can manage around 24 concurrent transfers - and the max heap size is usually set to 1GB.

Cheers
