It went all well, but suddenly, the server keeps increasing its memory usage. In this case, the player slows down, and the delay increases. The delay of the video could be up to 1 minute. The resident memory used by the server could reach ~20 megabytes(usually it only cost ~1 megabyte). It is hard for
me to inspect the internal memory usage of the server. Can you shed some light on the issue?</span></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;"><span><br></span></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;"><span>Thanks,</span></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal;"><span>Lan Zang(Sander) </span></div><div><br></div> <div style="font-family: 'times new roman', 'new york', times, serif; font-size: 12pt;"> <div style="font-family: 'times new roman', 'new york', times, serif; font-size: 12pt;"> <div dir="ltr"> <font size="2" face="Arial"> <hr size="1"> <b><span
