OpenJ9 (Java 8) 0.9.0 crashed with 'Inconsistency detected by ld.so'

[akrus]

Hello!

Just had a strange JVM crash. A few seconds after the service start-up (it was establishing the connections at that time) it crashed with the following line:

Inconsistency detected by ld.so: ../elf/dl-tls.c: 481: _dl_allocate_tls_init: Assertion `listp->slotinfo[cnt].gen <= GL(dl_tls_generation)' failed!

No other messages are available.

Some possibly useful details:

Unfortunately there is no core dump or anything else that could help.

Probably this is related:

It certainly looks like that glibc bug. The only thing I can think of is to reproduce with LD_DEBUG=all and see if that highlights where the issues occurs in openj9 to see if we can work around it.

[akrus]

I'll check if I can reproduce this bug as it just appeared for the first time.

It looks like a workaround is to use a static build.

Closing this as a glibc bug. Please reopen if it reoccurs and there's something we can do to help work around it.
