From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux ppc; rv:1.7.3) Gecko/20041014 Firefox/0.10.1 Description of problem: There was a deadlock bug in full data journaling for ext3 in 2.4.21 that got fixed aroud 2.4.23 iirc. This bug still exists in RHEL kernel and is making it unusuable for busy mailservers, for example. Version-Release number of selected component (if applicable): kernel-2.4.21-20.EL How reproducible: Always Steps to Reproduce: 1.Configure ext3 with data=journal and large external journal 2.Run bonnie++ on it with data size about 10 times the amount of ram Actual Results: System reproducibly freezes, usualy in the "writing inteligently" stage. Expected Results: Bonnie++ run should finish as expected. Additional info: I tested this on single cpu machine with 384mb ram, uniprocessor kernel, system on ide drive, ext3 partition in question on one scsi drive and its external journal on another scsi drive. The external journal I created is 400mb.
