Easybuild fails to build (ssl.SSLError: [SSL] malloc failure (_ssl.c:2805))

[adrianreber]

Trying to build Easybuild in the OpenHPC build system currently only fails on Leap x86_64 (works on aarch64) with following error:

It seems this is not an Easybuild failure but somehow connected to OpenSSL and the underlying OS:

Just wanted to let you know. This can probably be just closed. But I wanted to open it for awareness.

This is indeed not an EasyBuild problem, it can probably be easily triggered with a small Python script as well. @adrianreber Did you figure out the underlying cause?

[adrianreber]

Really old kernel and building easybuild in a chroot with new userspace packages.

We fixed it by moving to a different builder.

This can be closed.
