If you look in libsmbclient.h, you'll find this:
* Set whether to use the same connection for all shares on a server.
* Some Windows versions appear to have a limit to the number
* of concurrent SESSIONs and/or TREE CONNECTions. In
* one-shot programs (i.e. the program runs and then quickly
* ends, thereby shutting down all connections), it is
* probably reasonable to establish a new connection for each
* share. In long-running applications, the limitation can be
* avoided by using only a single connection to each server,
* and issuing a new TREE CONNECT when the share is accessed.
smbc_setOptionOneSharePerServer(SMBCCTX *c, smbc_bool b);
If you set this option to true, your problem should go away.
