ASE SP 122 hitting SIGSEGV 11

hello,

i just migrated to ASE 15.7 sp122 from sp102 but I am having sigsegv 11 that causes ASE to freeze until i do a restart. The frequency is almost like every other day on my production.

Any clue?

I equally tried upgrading to SP 130 but ASE will not start on my test environment.
