Phillip Arcuri created GUACAMOLE-384:
----------------------------------------
Summary: Guacd crashes in buffer.c during stress test
Key: GUACAMOLE-384
URL: https://issues.apache.org/jira/browse/GUACAMOLE-384
Project: Guacamole
Issue Type: Bug
Components: guacd
Affects Versions: 0.9.12-incubating
Environment: GNU/Linux x86_64
Reporter: Phillip Arcuri
Priority: Blocker
In a stress test we kick off a SSH session every second. The session does a
minimal amount of work and exists after a few seconds. A ps -ef shows we have
2 to 6 instances running at one time. About 1 in 10 of the instances cores
with corrupted buffer data at line buffer.c:108.:
(gdb) p *buffer
$2 = {default_character = {value = -1269703408, attributes = {bold = 170,
reverse = 42, cursor = false, underscore = false, foreground = 0,
background = 0}, width = -1269422328}, rows = 0x2aaab456fa30, top = 686,
length = 0, available = 686}
As an aside I also see roughly 1 in 100 instances become a zombie process hung
in pthread_join. Doubt that is related, but thought I'd mention it.
This is a blocker for our deployment of a guacamole-enabled feature-set.
