lws_smd_message_pending: timing out queued message 0x18f9ca0?

[bethebest0622]

my program run a long time with libwebsockets, it's stable and fast.

but today, i found this warning first time:

[2024/04/14 19:04:05:8267] W: lws_smd_message_pending: timing out queued message 0x18f9ca0

Does this mean there are too many messages in queue? How can i avoid this?

more information: I have 40 processes, each process may lws_write(). (40 processes is neccessary for me, because i want it runs parallelly)
