** [tickets:#1446] log: trouble when the number of existing app streams reachs
limitation**
**Status:** fixed
**Milestone:** 4.6.2
**Created:** Thu Aug 13, 2015 10:10 AM UTC by Vu Minh Nguyen
**Last Updated:** Thu Mar 17, 2016 08:56 AM UTC
**Owner:** nobody
When creating an configurable app stream (e.g: using `immcfg –c`). Suppose all
inputs are valid.
In this case, logsv returns `SA_AIS_OK` to IMM for its callbacks. Means IMM is
allowed to creates its database/resource for this obj (*1*).
In apply callback, IMM asks logsv to apply the change – not require acknowledge.
If number of app streams has reached the limitation - defined by
`logMaxApplicationStreams`, logsv will get failed to add this stream to
stream_array.
As the result, logsv deletes all allocated resources managed by itself. The
created resources in step (*1*) is still existing. And it causes things as
below – see my comments in right side:
1. Create obj successfully from IMM. But actually, logsv gets failed at
ccbApplyCallback
> immcfg -c SaLogStreamConfig safLgStrCfg=test6 -a saLogStreamPathName=. -a
> saLogStreamFileName=test6
2. immlist failed as logsv returns not ok `no such obj` to IMM.
> immlist safLgStrCfg=test6
error - saImmOmAccessorGet_2 FAILED: SA_AIS_ERR_NO_RESOURCES (18)
3. Create obj failed as the resource is existing
> immcfg -c SaLogStreamConfig safLgStrCfg=test6 -a saLogStreamPathName=. -a
> saLogStreamFileName=test6
error - saImmOmCcbObjectCreate_2 FAILED with SA_AIS_ERR_EXIST (14)
