_aiowrite() returning EAGAIN

Hi, I have 2225 messages *** _aiowrite() returning EAGAIN *** and 22 messages KAIO: out of OS resources, errno = 11, pid = 17644 in my online.log file for about 5 mins period. During this period of time, the system was working as usualy. The only difference was I created several index for two new tables. Both, indexes and tables were created in newly added (yesterday) dbspaces histdbs and ihistdbs and they are in infomrix mirroring configuration. There aren't any errors in the OS system log. Have I lost any of my data? What's the reason of such a messages (errors?)? Maybe I must change some ONCONFIG parameters to avoid this situation again.
