Hi all,
I'm investigating high memory usage of my program: RSS varies between
executions in range 20-50 GB, though it should be determenistic. I've
found that all the memory is allocated in this stack:
Allocated 17673781248 bytes in 556 allocations
cds_lfht_alloc_bucket_table3 from liburcu-cds.so.2.0.0
_do_cds_lfht_resize from liburcu-cds.so.2.0.0
do_resize_cb from liburcu-cds.so.2.0.0
call_rcu_thread from liburcu-qsbr.so.2.0.0
start_thread from libpthread-2.12.so
clone from libc-2.12.so
According pstack it should be quiescent state. Call thread waits on syscall:
syscall
call_rcu_thread
start_thread
clone
We use urcu-0.8.7, only rculfhash (QSBR). Is it some kind of leak in
RCU or any chance I misuse it? What would you recommend to
troubleshoot the situation?
P.S. sorry if this email received multiple times: I'tried twice from
my work email and after few hours didn't notice the email in the list.
