Ken Giusti updated DISPATCH-1135: --------------------------------- Labels: memory-bug (was: ) > Router A leaks memory when router B killed and restarted. > --------------------------------------------------------- > > Key: DISPATCH-1135 > URL: https://issues.apache.org/jira/browse/DISPATCH-1135 > Project: Qpid Dispatch > Issue Type: Bug > Reporter: Michael Goulish > Priority: Major > Labels: memory-bug > > I set up a 2-node router network, with B connecting to A. > No clients. > Repeatedly killing and restarting B – giving 3 seconds after each kill and > after each restart for the network to settle down. Repeated 100 times. The > same router A ran for the duration of the test. > The 'ps' program, run repeatedly on router A, indicated that it was leaking > about 82 KB per kill-and-restart. Using 'qdstat m' on A after each > kill-and-restart showed the following difference between iteration 1 and > iteration 100. ( Note, this shows growth of only 44 KB per iteration. ) > > As far as I looked into the past (about 1 year) I saw similar behavior. > > In the chart below, the first column "size" is the number of bytes in a > single struct of that type. > "In-threads" means how many of each struct are currently being used. > > Note that, although there are no clients, the routers will be sending some > messages to each other. > > > {{type size in-threads in-threads item byte}} > {{ test 1 test 100 growth growth}} > {{ ======================================================================}} > {{qd_buffer_t 536 256 2944 2688 1440768}} > {{ qd_message_content_t 1056 128 1216 1088 1148928}} > {{ qd_iterator_t 160 448 7488 7040 1126400}} > {{ qd_parsed_field_t 88 256 2880 2624 230912}} > {{ qdr_delivery_t 248 256 1152 896 222208}} > {{ qd_message_t 160 256 1088 832 133120}} > {{ qd_connection_t 2320 32 64 32 74240}} > {{ qdr_general_work_t 64 64 448 384 24576}} > {{ qdr_link_t 360 192 256 64 23040}} > {{ qd_bitmask_t 24 192 1088 896 21504}} > {{ qdr_connection_work_t 48 64 384 320 15360}} > {{ qdr_link_work_t 48 64 384 320 15360}} > {{ qd_link_t 96 128 256 128 12288}} > {{ qdr_link_ref_t 24 64 448 384 9216}} > {{ qd_parsed_turbo_t 64 128 256 128 8192}} > {{ qd_link_ref_t 24 64 256 192 4608}} > {{ qdr_error_t 24 64 256 192 4608}} > {{ qd_deferred_call_t 32 64 192 128 4096}} > {{ qdr_terminus_t 64 192 256 64 4096}} > {{ qdr_delivery_ref_t 24 64 128 64 1536}} > > ( All other structs have zero growth.
