MAX SERVER THREADS

TCP/IP-channel-specific options: MAX_SERVER_THREADS (integer; &#x3c;= 47 on Solaris)
This TCP/IP channel SMTP/LMTP server option has little relevance today, and the little effect is does have is Solaris-specific. (Formerly, for the PMDF, pre-Dispatcher multithreaded SMTP server, it controlled the maximum number of simultaneous, inbound connections that the pre-Dispatcher multithreaded SMTP server program would allow. Note that since only one such server process was allowed, this option effectively controlled the total number of simultaneous, inbound SMTP connections that older versions of PMDF could handle.) Nowadays, this option&#x27;s sole effect is that on Solaris only,  it is taken into account in deciding the maximum number of file descriptors allowed for an SMTP server process. Since this value is multiplied by 5 and then 20 added, the effect of the default of 40 is that a maximum of 220 file descriptors are allowed.

The default value is 40. Note that setting a value of 48 or more on Solaris will cause the server process to exit with an error.
