I've enclosed a reply to Gregory Grosshans (also of NOAA) on just this issue that I answered just this morning. Take it as applying 100% to your situation, too. Basically, I need and would like some help to solve this problem. Regards, Steve Emmerson

The LDM 6 package builds under HP-UX 11 but the LDM fails shortly after startup with a out-of-memory error that is not seen on any other platform: $ uname -a HP-UX tweety B.11.00 E 9000/785 2004553471 8-user license $ rpc.ldmd -vl- -q data/ldm.pq etc/ldmd.conf Jun 10 14:43:11 rpc.ldmd[25494]: Starting Up (version: 6.0.12; built: May 21 2003 13:11:59) Jun 10 14:43:11 emo[25495]: Starting Up(6.0.12): emo.unidata.ucar.edu: TS_ZERO TS_ENDT {{EXP, ".*"}} Jun 10 14:43:11 emo[25495]: Desired product class: 20030610134311.946 TS_ENDT {{EXP, ".*"}} Jun 10 14:43:11 emo[25495]: Connected to upstream LDM using protocol version 6 Jun 10 14:43:11 emo[25495]: Upstream LDM is willing to feed Jun 10 14:43:11 emo[25495]: svc_fd_create: No memory!

Unfortunately, the kernel must be rebuilt in order to change this parameter and we've been unsuccessful in our attempts to do this so far. Any help you can give with this problem would be appreciated. Just FYI, the LDM 6 package runs successfully on the following systems (which we have in-house): AIX 5.1, AIX 4.3, FreeBSD 4.5, FreeBSD 4.7, IRIX 6.5, IRIX64 6.5, Linux 2.4.18, OSF1 V5.1, SunOS 5.8 (sparc), SunOS 5.8 (i86pc). > Thanks, > Gregg Grosshans > NCEP/Storm Prediction Center Regards, Steve Emmerson
