- Subject: static TLS exhausted on ppc64le
I would like to open a problem we have already met twice in Fedora. the
"/lib64/libgomp.so.1: cannot allocate memory in static TLS block"
usually when loading a lot of libraries/modules into a Python
application. It happened on ppc64le and also on aarch64 systems.
We have 2 reports in Fedora bugzilla about with more details.
We have already discussed that briefly with Florian and other members of
the Red Hat toolchain team, but outcome was in form of a recommendation
to reduce the usage of "static TLS" objects in the individual libraries.
But the open question still is - is there a fix for the TLS space
exhaustion? I believe it can easily become a more serious problem soon.
