Hello, 

I am using Boost.Log to produce 2 logs for a multi-thread application.

There are 2 singleton channel_mt loggers corresponding to 2 files. 

Several threads continuously write different messages to the two loggers. 

Log file rotation is enabled on both loggers and in the event of rotation, the logs are collected into a different folder. 

All of this works as expected for a while, except randomly (but surely at some point) - I start seeing a stream of messages like - 

[2015-Jul-17 01:11:26.532653] (info): *** Exception: boost::filesystem::last_write_time: No such file or directory: "/var/infinity/rtb/auction_log"

[2015-Jul-17 01:11:26.532896] (info): Boost Exception - libs/log/src/text_file_backend.cpp(1160): Throw in function void boost::log::v2_mt_posix::sinks::text_file_backend::consume(const boost::log::v2_mt_posix::record_view&, const string_type&)

This goes on for a while and then my application hangs.

It is not entirely clear whether this incidence happens only during size based rotation or even otherwise.

Any pointers on how to approach this issue would be greatly appreciated.

Thanks

Raj
