Re: Block in ldap_result call, even after specifying some finite time limit

Hi Anton,

We are using Mozilla LDAP C SDK version 5.12. NSPR version is 4.2.2.
NSS version is 3.7.7. We encountered this problem on Windows. We have
not verified it on other platforms.

And, I was not talking about PR_Recv call. Here is the stack trace,
where we observed the block
