Service normal, test commands
[root@push-5-217 src]# omreport chassis memory Memory Information Error : Memory object not found
After restarting the service, and then test, still returns an error,
Second, to see whether the signal reached the upper limit
1, view the current limit signal is provided
[@ Push- the root . 5 - 217 the src] # the ipcs - SL --------- ----------- semaphore limit the maximum number of array = 128 the maximum number of each array semaphore = 250 the maximum number of semaphore system = 32,000 per call semaphore maximum number of operations = 32 semaphore maximum = 32767
The maximum number of array 128
2, the signal has been used to view
[@ Push- the root . 5 - 217 the src] # the ipcs - US --------- ----------- state semaphore used array = 128 signal assigned number = 140
It can be seen has been used 128 array, the limit has been reached.
3, see who used the annunciator
[root @ Push- 5 - 217 src] # ipcs - the p- --------- ----------- message queue PID msqid lrpid owner LSPID -------- shared memory creator / last modified ---------- PID shmid owner LPID CPID 65536 zabbix 17461 15977
4, upper limit value setting modification signal
[root@push-5-217 src]# cat /proc/sys/kernel/sem 250 32000 32 128
Current setting value 128
[root@push-5-217 src]# sysctl -w kernel.sem="250 32000 100 256" kernel.sem = 250 32000 100 256 [root@push-5-217 src]# cat /proc/sys/kernel/sem 250 32000 100 256
Revised to 256
250 32000 100 256 [Push the root @ - . 5 - 217 the src] # the ipcs - SL --------- ----------- semaphore limit the maximum number of array = 256 of each array The maximum number of semaphore = 250 the maximum number of semaphore system = 32,000 per semaphore maximum number of operations invoked = 100 semaphore maximum = 32767
At this point, the signal is the upper limit has been expanded to 256, and then run the command
