Howdy, I'm running pgbench with a fairly large # of clients and getting this error in my PG log file.
Here's the command: ./pgbench -c 1100 testdb -l I get: LOG: could not send data to client: Broken pipe (I had to modify the pgbench.c file to make it go that high, i changed: MAXCLIENTS = 2048 I thought maybe i was running out of resources so i checked my ulimits: ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) unlimited max locked memory (kbytes, -l) unlimited max memory size (kbytes, -m) unlimited open files (-n) 2048 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) unlimited real-time priority (-r) 0 stack size (kbytes, -s) unlimited cpu time (seconds, -t) unlimited max user processes (-u) unlimited virtual memory (kbytes, -v) unlimited file locks (-x) unlimited This is Pg 8.3.10. Redhat 64bit, the system has 48 cores, 256G of ram.. Any idea what would be causing the error? thanks Dave -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
