Linux – Ext3 Keeps getting Journal Error and Becoming Read-Only

I have a RHEL5.5 x86_64 server with 2 HBA connecting to EMC and HP storage arrays. EMC PowerPath is installed because my EMC vendor insists on that.

My problem is the volumes on HP storage often get journal error (see below) and goes into read-only mode.

Is it a SAN problem or OS problem? How can I resolve this?
