Any idea why GDB is accessing all those directories?  I cannot know
what kind of directory structure you have there, and so cannot reason
about the directories being accessed by GDB or whether it should
access some directory.  What are those directories, and why
symbol-file causes GDB to access them?

That is probably the real culprit: some directory that needs some
special credentials, or which causes GDB to call some network-related
resources which are inaccessible or something.  So understanding why
GDB tries to access that directory and/or making its access faster,
might fix your problem.

Which ones?
