Sometimes our users doesnt get the files from an attachment pool.

When this happens, the midtier log writes the error below. After 10 minutes the attachments go fine until the next time it fails again.

This error has a frequency of 4 times for day. So it makes my users dont use the attached files for 40 minutes / day.

Its a Midtier 7.5 patch 2 on weblogic.

¿Any ideas?¿Someone with this version over weblogic without problems?

Thank you.
