[rhmessaging-commits] rhmessaging commits: r2070 - store/trunk/cpp/lib/jrnl.

Author: kpvdr Date: 2008-05-20 15:13:03 -0400 (Tue, 20 May 2008) New Revision: 2070 Modified: store/trunk/cpp/lib/jrnl/jcntl.cpp Log: Fix for BZ444593: "_st_read.increasing_interval_delayed_read test fails intermittently with RHM_IORES_RCINVALID on qpid-test4". On slow and busy disk systems, the wait loop can exhaust its wait count prematurely and throw an RHM_IORES_RCINVALID while the disk is trying to catch up on previous writes and for the initial file header read of the read synchronization to take place. The wait period was increased from 2ms to 5ms and the count from 50 to 500 (based on observations made on some slow disk systems).
