I just had another case of this issue on a different box,
this time running fetchmail 6.3.18.

Here's all the info I was able to collect:

Log from fetchmail:
fetchmail: POP3< +OK Capability list follows
fetchmail: POP3< TOP
fetchmail: POP3< USER
fetchmail: POP3< UIDL
fetchmail: POP3< STLS
fetchmail: POP3< SASL PLAIN
fetchmail: POP3< IMPLEMENTATION trinity
fetchmail: POP3< .
fetchmail: POP3> STLS
fetchmail: POP3< +OK Begin TLS negotiation

fetchmail was stuck at that line since 21.04.2011.

Even though I installed the -debuginfo packages,
I wasn't able to get a meaningful backtrace.

So the stall happens before the authentication state?

Cheers,
