My Server CPU is at 100 percent and not responding using PUMA and Nginx after one or two days. I use 4 workers. Up to now I had a look at the problem with strace, which leads to the following Output

futex(0x20f0f64, FUTEX_WAKE_OP_PRIVATE, 1, 1, 0x20f0f60, {FUTEX_OP_SET, 0, FUTEX_OP_CMP_GT, 1}) = 1 futex(0x20f0f30, FUTEX_WAKE_PRIVATE, 1) = 1 futex(0x20f0f98, FUTEX_WAKE_PRIVATE, 1) = 1 futex(0x20f0f9c, FUTEX_WAIT_PRIVATE, 2376235, NULL) = -1 EAGAIN (Resource temporarily unavailable)

A look at the FD showed that the Resource her is "puma.sock" Does anyone has an idea how to get closer to the problem?
