llama-server bug caused long request delays, now fixed

A bug in the llama-server's HTTP handling, specifically within the cpp-httplib library it uses, could cause significant delays for some user requests. When a large number of keep-alive connections were open, a new connection's request might not be processed for up to 42 seconds. This issue was rare, affecting only one connection at a time and often occurring on a freshly started server. The problem has been resolved in recent versions of llama.cpp (b11737 and later) due to a fix in cpp-httplib. AI

IMPACT Fixes a rare but significant latency issue for llama-server users, improving reliability for applications like chat UIs and agent frameworks.
