SuSe Linux BOE XI R3 SP3 Webi Processing Server unstable

I met a serious problem last week. My client has upgrade their BOE XIR 3 SP2 to SP3, and after the upgrade process, webi processing servers seem not stable. A "Failed" status for the processing servers thrown. I have tried to restart it manually and it still shows the Failed status.

And this happens randomly, not refreshing particular report or something else will still give the error.

I have also checked the log file. Here is the log message segment:

kc3_bo_intl_wstring.cpp:777:static bo_wstring c3_intl::Context::GetDominantLocale(const bo

Totally lost my mind. Your help might help me out.

Thanks in advance.
