Ganesh Murthy closed DISPATCH-64. --------------------------------- > slow or sporadic memory leak > ---------------------------- > > Key: DISPATCH-64 > URL: https://issues.apache.org/jira/browse/DISPATCH-64 > Project: Qpid Dispatch > Issue Type: Bug > Reporter: michael goulish > Priority: Major > > In long-term soak tests, I am seeing router mem grow by 1 megabyte every 4 or > 5 minutes. > Test setup > ======================================= > 1. single router on one box > 2. 10 senders, 10 receivers on separate box. > 3. each client handles 100 unique addresses. > 4. while test is running, I run 'top' in a loop to see router memory usage > (resident set size). I also run "qdstat -m" in a loop, to see router's > report on usage of various data structures. > 5. clients all have single connection for duration of test. > 6. clients start once at beginning of test and do not stop until end. No > new clients are started after the beginning. > 7. no clients failed during the test. > 8. no new addresses were added after test startup. > Observations > ========================================= > 1. During a 64 minute period which started at least 15 minutes after the > beginning of the test, memory usage (resident set size) as measured by 'top' > grew from 96 to 109 megabytes. > 2. Some of the data types reported by 'qdstat -m' increased. Here is the > list: (using numbers from the 'total' column of qdstat report. ) > qd_connection_t 832 --> 896 > qd_hash_handle_t 1408 --> 1600 > qd_hash_item_t 1408 --> 1600 > qd_link_t 1536 --> 1664 > qd_log_entry_t 1152 --> 1216 > qd_message_content_t 10256 --> 10272 > qd_parsed_field_t 448 --> 1024 > qd_router_link_ref_t 1408 --> 1600 > qd_router_link_t 1536 --> 1664 > 3. The data structures that increased did *not* increase smoothly. For > example, qd_hash_handle_t and qd_hash_item_t remained constant for 6 minutes > before increasing. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
