Subject java.io.IOException: Too many open files (v5.4.2)
Date Thu, 17 May 2012 22:07:40 GMT
We’re running *ActiveMQ 5.4.2 *in production. The last few days we’ve had
clients unable to connect because of the /java.io.IOException: Too many
open/ files error. We’ve been able to temporarily solve the problem by
increasing the maximum heap size, however, the problem seems to come back a
few days later.

Do you have any suggestions how on we can more reliably solve this problem? 

Do we need to consider upgrading our production server?

Thank you for your time in advance.

John Boyer
