I am getting an error which prevents valgrind from starting. I am running kernel 2.6.32.22 under Ubuntu 10.04
==10577== ==10577== Valgrind's memory management: out of memory: ==10577== newSuperblock's request for 4194304 bytes failed. ==10577== 14356480 bytes have already been allocated. ==10577== Valgrind cannot continue. Sorry. ==10577== ==10577== There are several possible reasons for this. ==10577== - You have some kind of memory limit in place. Look at the ==10577== output of 'ulimit -a'. Is there a limit on the size of ==10577== virtual memory or address space? ==10577== - You have run out of swap space. ==10577== - Valgrind has a bug. If you think this is the case or you are ==10577== not sure, please let us know and we'll try to fix it. ==10577== Please note that programs can take substantially more memory than ==10577== normal when running under Valgrind tools, eg. up to twice or ==10577== more, depending on the tool. On a 64-bit machine, Valgrind ==10577== should be able to make use of up 32GB memory. On a 32-bit ==10577== machine, Valgrind should be able to use all the memory available ==10577== to a single process, up to 4GB if that's how you have your ==10577== kernel configured. Most 32-bit Linux setups allow a maximum of ==10577== 3GB per process. ==10577== ==10577== Whatever the reason, Valgrind cannot continue. Sorry. $ ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 20 file size (blocks, -f) unlimited pending signals (-i) 16382 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) unlimited virtual memory (kbytes, -v) unlimited file locks (-x) unlimited
