Dear Jochen,

Thank you for suggesting the valuable URL, we are getting 3 "floating point
assist fault" error for every second, will it impact the performance for
postgresql?

Is there any option to turn on "flush to zero mode" in itanium cpu while
compiling postgresql from source?

Thank you for your valuable time to read this.

Regards,

Muthu
