Description

The sqlops module run into an infinite loop and print continously this line to the stderr (or stdout):

22(17903) ERROR: [core/io_wait.h:1040]: io_wait_loop_epoll(): epoll_wait(10, 0x2ab72bb7b690, 0, 5000): Invalid argument [22]

Troubleshooting

Reproduction

Set log_stderror=yes
Load the sqlops module and configure it with a bad DB host.

Example:

log_stderror=yes
loadmodule "sqlops.so"
modparam("sqlops","sqlcon","main=>postgres://abc:abc@INVALID_HOST/test")
