[jboss-jira] [JBoss JIRA] Commented: (JBAS-7102) Problem sending large files via farm service

[ https://jira.jboss.org/jira/browse/JBAS-7102?page=com.atlassian.jira.plug... ] Brian Stansberry commented on JBAS-7102: ---------------------------------------- I've added a test that farms a 150MB file[1] and it passes, with the test taking < 25 secs to run (which includes time to write out the 150MB file). I'll comment in more detail on the forum thread, but here are a couple suggestions: 1) Stop the hot deployment scanner thread before doing lengthy I/O operations (e.g. copying in files) in the farm/ (or deploy/) folders. Then restart it when I/O is done. This avoids the hot deployment scanning running and seeing partially completed I/O. The scanner can be stopped by invoking the JMX stop() operation on the jboss.deployment:flavor=URL,type=DeploymentScanner MBean. This can be done via the jmx-console or via the twiddle utility in $JBOSS_HOME/bin. 2) Make sure your network is tuned to limit losses of UDP packets. Among other things, increase the OS maximum network read and write buffers; e.g. on Linux sysctl -w net.core.rmem_max=26214400 sysctl -w net.core.wmem_max=1048576 [1] https://svn.jboss.org/repos/jbossas/branches/Branch_5_x/testsuite/src/mai... -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
