I thought we had a major network problem when servers started seeing "dropped packets" as shown on the query vswitch and lost putty sessions and http timeouts. We had migrated to LACP vswitch, 5.4, and put in a new LPAR all around the same time so it was hard to narrow down. Turns out Class A had been lost on the ID that ran the set srm storbuff command.
Maybe I should have let them stare at the dumps for a few more weeks ;) What a nice (albeit exasperating) feeling when a simple commands makes problems vanish immediately! You get that satisfaction all the time I bet! I would think that IBM would want to change it for that reason alone :) Marcy "This message may contain confidential and/or privileged information.

If it is, the best fix for this is to set new SRM STORBUFF parameters. If you don't have access to MAINT, you probably do not have the authority to set the SRM STORBUFF parameters yourself anyway. > > Mike > > C. M.

There should be several hits in the list archives on dispatching, over-committing, SRM, etc. You will probably need to modify STORBUF and/or LDUBUF.

Don't know what it is and don't know how to diagnose it. Being a real newb I could use some help. We just use this system to maintain another system so know very little about linux. I got it running a couple of years ago and that was fun but had to get back to my real job so have spent very little time with it. > > Thanks > Warren Taylor > > > ---------------------------------------------------------------------- ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
