Hello, I have a proxy that uses Boost.Asio, everything normal so far, only began to appear a strange problem. Sometimes, the proxy stops responding. I make a connection to it, send the request and it returns nothing. Sometimes he does not 'accept' the connection, it seems that goes into some waiting list. Could generate a core dump when it is 'locked', follows the text of the gdb backtrace. Attached the 'backtrace full'. _____ #0 0x00002adcec8a9cd8 in epoll_wait () from /lib/libc.so.6 #1 0x00000000005dedd3 in boost::asio::detail::epoll_reactor<false>::run (this=0x2adcf0000c90, block=true) at /usr/include/boost/asio/detail/epoll_reactor.hpp:470 #2 0x00000000005db050 in boost::asio::detail::task_io_service<boost::asio::detail::epoll_reactor<false>
