We started getting huge numbers of these messages on one of our OSS servers, there are two OSS servers in the system each with 2 OSTs on them. The second OSS does not generate these messages.

Mar  5 08:20:20 rt-oss1 kernel: LustreError: 29297:0:(fsfilt-ldiskfs.c:493:fsfilt_ldiskfs_brw_start()) want too many journal credits (555) using 500 instead

Mar  5 08:20:20 rt-oss1 kernel: LustreError: 29297:0:(fsfilt-ldiskfs.c:493:fsfilt_ldiskfs_brw_start()) Skipped 16215 previous similar messages

Does anyone know what this message is about? Since we started getting them the lustre system performance has been reduced.
