> OpenBLAS blas_thread_init: pthread_create failed for thread 7 of 16: Resource temporarily unavailable

16 threads is not much so that alone isn't the issue. However https://github.com/xianyi/OpenBLAS/issues/1668 mentions that the offending code might have set the stack ulimit to gigabytes in size, which would make the system quickly run out of virtual address space when creating new threads. Although I doubt the offending "LSF" code is something totem uses, your issue does also look like it has run out of address space for new thread stacks.
