- In v11.6.1, bigd reports pool members were marked down that are not actually down, and logs messages similar to the following in the ltm log file: warning bigd[7413]: 01060154:4: Bigd PID 7413 throttling monitor instance probe because file descriptor limit 65436 reached. - Because of changes in the v12.1.x software, although the problem is still present, it has negligible impact.
- On v11.6.1 this can cause bigd to stop monitoring, resulting in pool members being marked down erroneously. - In v12.1.x, some of the underlying logging code changed, and there is no real impact.
-- Monitoring is in use. -- bigd debug logging is enabled. -- The bigd debug log file (/var/log/bigdlog) is full.
Prevent the log file from getting full. To do so, rotate the log file using the following command: logrotate -f bigdlog
Stopped bigd from thinking it was out of file descriptors when it was unable to open its debug log file.
