James, > Yesterday I upgraded to ldm6.4.5 from version 6.4.1. On my backup > server, I pick up WSI radar imagery (data also coming from primary > server). Anyway, I stopped receiving WSI radar early this morning > (after 1255 GMT) although the Unidata data came in fine. When I > contacted WSI, the technician told me he was receiving a SIGPIPE error. Can you get me the relevant log entries on the WSI system? > The lone log statement by ldm (around the time the radar stopped coming > in) was the following: > > Apr 14 12:48:57 peridot pqact WARN: write(7,,5120) to pipe took > 2.312377 s This isn't a problem. It indicates that the pqact(1) process took about 2.3 seconds to write 512 bytes into the pipe for the decoder process. Undoubtably, the computer was busy doing other things. > When I reverted back to ldm6.4.1 on the backup server (primary still on > newer version), the WSI radar was coming in fine again. Do you have a > possible explanation for this? The radar did come across fine for awhile > after the upgrade, and even after WSI radar stopped, other data > (satellite, model, surface/upperair, etc) continued without problems. I > only changed the ldm program (no change to the ldmd.conf file). I have no explanation for the occurrence. Note, however, that the problem might not be the new LDM installation -- with one data point it's impossible to tell. Can you send me your LDM logfile from just before the problem to just after? > James > > -- > ---------------------------------------------- > James Murakami > Staff Meteorologist/Student Affairs > Department of Atmospheric and Oceanic Sciences > University of California, Los Angeles > 405 Hilgard Ave. > Los Angeles, CA 90095-1565 > > > e-mail: address@hidden > telephone: 310-825-2418 > Fax: 310-206-5219 Regards, Steve Emmerson Ticket Details =================== Ticket ID: TXO-622416 Department: Support LDM Priority: Normal Status: Closed
