No buffer space available error in IBM Content Collector logs

Troubleshooting


Problem

IBM Content Collector (ICC) task route stops processing or comes to a halt after running for a few days. Problem continues even after restarting the services.

Symptom

"No buffer space available" error can be seen in multiple places in the IBM Content Collector logs.

For example, it could be in the CM8 connector log:

It could also be in the email connector log:

See the following message: com.ibm.afu.mailinterface.MailException: javax.naming.CommunicationException: host:domain.com:3268 [Root exception is java.net.SocketException: No buffer space available (maximum connections reached?): connect] [com.ibm.afu.mailconnector.AbstractConnectorService initMailinterface] [pool-2-thread-1 0]Exception [com.ibm.afu.mailinterface.MailException]: javax.naming.CommunicationException: host.domain.com:3268 [Root exception is java.net.SocketException: No buffer space available (maximum connections reached?): connect]
