[B.A.T.M.A.N.] batman-exp still has sometimes around 90% CPU load

[Stephan Enderlein (Freifunk Dresden)]

Hi,

I'm using batman-experimental rev1145. I test this release since
2 days. I found that a thread of batmand was consuming around 90%
of cpu resources.

Mem: 15064K used, 15560K free, 0K shrd, 1152K buff, 5176K cached
CPU: 10.0% usr 90.0% sys  0.0% nice  0.0% idle  0.0% io  0.0% irq  0.0%
softirq
Load average: 0.98 1.00 0.97
  PID  PPID USER     STAT   VSZ %MEM %CPU COMMAND
 4464  1941 root     R     1216  3.9 84.1 /sbin/batmand -s 10.12.0.1  -a
10.12.10.16/28 -r 1 --t 63 --no-unreachable-rule --no-throw-rules
 1151     1 root     S     1216  3.9  0.0 /sbin/batmand -s 10.12.0.1  -a
10.12.10.16/28 -r 1 --t 63 --no-unreachable-rule --no-throw-rules
 1941  1151 root     S     1216  3.9  0.0 /sbin/batmand -s 10.12.0.1  -a
10.12.10.16/28 -r 1 --t 63 --no-unreachable-rule --no-throw-rules

it was not possibe to connect to the running batmand.
A call "batmand -c" just hangs without printing current parameters.

I had this error in previous revision where you disabled the debug task.
Batmand was running without problems.Have you enabled the debug task again
in current revision?

any idea or solution?
Regards
 /Stephan

Well, the debug functionality has never been disabled. It has just been moved 
to the main thread. Iam already thinking whether it makes sense to do the 
same with the tunnel thread - but not tonight. According to your debug output 
Iam sure its the tunnel thread. Just wondering why the same peace of code 
works since days on several mipsel and x86 devices here. Please test with 
r1146.

cheers,
axel

Hi,

I will try the release 1146. Just for information I use the following
compile/linker switches:

CFLAGS =        -Wall -O1 -DMEMORY_USAGE -DPROFILE_DATA -DDEBUG_MALLOC
LDFLAGS =       -lpthread


Cheers,
 Stephan
