Faster RSA in Java with GMP
Square Engineering

Hello. At first, thanks for the great job.

We modified our RSA implementation, so our service could sign some data faster. But later this application started crashing down because of high amount of signing operations. In a crash log we found this:

# Problematic frame:
# C [jna173233083546994264.tmp+0x71e58] __gmpn_sec_powm+0x248

Sometimes it could work for several days, sometimes only for a few hours.

Have you had something like that?
