Deadlock bug in ssl library

[Inswitch Solutions]

Hi,

Which OS are you using?
Some time ago I have had problems with the SSL port (ssl_esock) with Yaws in Win32 and when sending data to the server. Perhaps it's related with yours.
By increasing the buffer size of the C/C++ port and with some other changes I've managed to work it out for small size data uploads.  There're some postings in the list with the changes I made.

Hope it helps.

regards, Eduardo
