287 // In general, a hang in error handler is much worse than a crash or internal | |
288 // error, as it's harder to recover from a hang. Deadlock can happen if we | |
289 // try to grab a lock that is already owned by current thread, or if the | |
290 // owner is blocked forever (e.g. in os::infinite_sleep()). If possible, the | |
291 // error handler and all the functions it called should avoid grabbing any | |
292 // lock. An important thing to notice is that memory allocation needs a lock. | |
293 // | |
294 // We should avoid using large stack allocated buffers. Many errors happen | |
295 // when stack space is already low. Making things even worse is that there | |
296 // could be nested report_and_die() calls on stack (see above). Only one | |
297 // thread can report error, so large buffers are statically allocated in data | |
298 // segment. | |
